We can derive the H \(\alpha \)  extinction that [1]} would predict
and compare this to our results.
They obtained \(K\) -band extinctions \(A_K=0.74\) , 0.22, and 0.0030 mag
for \(M_{\mathrm {p}}=0.48\) , 0.95, and 2.38 \(M_{\mathrm {J}}\)  respectively (E. Sanchis 2021, pers. comm.). With the opacity law they used [2]},
this translates to \(A_{\mathrm {H}\,\alpha } \approx 5.3\) , 1.6, and 0.021 mag respectively.
